SHUTTER STAY AND ADJUSTER.

Patented Dec. 24, 1907.

Application filed October 31,1903. Serial No. 179.385.

To all whom it may concern:

Be it known that I, THOMAS A. WESTON, a citizen of the United States of America, residing in Arden, county of Buncombe, State of North Carolina, have invented certain Improvements in Shutter Stays or Adjusters, of which the following is a specification.

My invention relates to frictional shutter stays or adjusters of the class illustrated in the specification of my United States patent of December 26th, 1899, No. 640,057, its object being'to further increase their efficiency and to extend their applicability, in particular to adapt them to the type of stays having a pivotal connection with the sill of the win dow for the controlling ofa single shutter.

My invention is obviously also intended for the better adjustment in like manner'of French windows, transoms, or other allied In the accompanying drawings Figure 1 is a plan View of my improved stay applied to a single shutter: Fig. 2 is a longitudinal elevation of the same partly in section: Fig. 3 isan elevation of the frictional bracket at right angles to Fig. 2: Fig. 4 is a central sectional view of the bracket showing the thumb screw withdrawn: Fig. 5 is a top plan view of the conical friction hub within the bracket: Fig. 5 is a bottom View of the disk above the conical hub: Fig. 6 is a transverse sectional view on the line 6-6, Fig. 2: Figs. 7 and 8 are side elevation and plan respectively of the friction pivoted stay hook: and Figs. 9 and 9 are horizontal and vertical sections of a modified stay hook.

M invention in its main parts comprises a frictional shutter bracket A secured to the single swinging shutter B, a sliding or telescoped two-part stay arm 0, D, a frictional clamp E thereon concentric to the axis of the -stay arm C, D, and a pivot pedestal E secured to the sill of the window by one central screw G, and a loose pin or pivot connection, whereby the bracket end of the stay arm C, 1), is pivoted to the rotatory friction hub or plug a within the bracket A. The axial movement of the said'plug combined with a possible movement when required of the stay arm in a plane at right angles upon the pivot a, together afford to the stay arm perfect freedom from cramping or bending when the shutter is swung, and which otherwise might occur from the sagging of the shutter .or from imperfect alinement in first attaching the bracket. In the bracket of my aforesaid U. S. patent the sliding stay arm or bar is rigidly attached to its rotating fric tional part at the said shutter bracket, whereby a cramping or bending action upon the stay bar is possible. A further advantage in the aforesaid detachable pivot connection of the stay arm or bar to the bracket, is the increased facility of first attaching the device to the shutter. The separate detached brackets are easy to handle and can be screwed to their places unencumbered by the stay bar. The sill pedestal E requires but one screw to attach it immovably to the sill, the device as shown in the drawings being self-adapting to .any slope or angle in the sill face without cutting the sill.

The concentric friction clamp E affords a convenient hand grip for pushing or pulling the attached shutter to and fro into the position.

The pivoted hook H by friction at its pivot (hereinafter described) will remain elevated out of action and clear of the stay arm,

. so as to allow a very slightly bowed position of the shutters without interference from the hook end dragging upon the stay. The hook is also a convenient means wherewith to pull the shutter firmly closed, and there lock it by pushing the hook down over the stay arm.

The shutter bracket A is conically shaped within to fit upon the conical plug or hub a for frictional engagement. The plug a has a thumb screw a threaded into it adapted to draw together the conical friction surfaces or to release them. A cap or collar 1 is engaged with the upper end of the ,plug a} by means of a rib or feather a upon cap 0, entering a groove or cross slot a in the plug end. The said rib and groove engagement insures simultaneous motion to both partsand prevents the unscrewing of the thumb screw by the swinging of the shutter. The lower end of the plug a has a wide transverse slot a to receive the end ofthe tube C and retain it upon the pivot pin a, upon' which pin the tube C has a limited angular movement to avert the cramping of the movingparts, as'

explained hereinbefore. This improvedform of frictional bracket with its hub or said prior patent, provides a ready swiveled attachment to the stay bar by a simple pivot pin affording a simple and inexpensive form of construction.

The sliding stay arm consists of an exterthe pedestal E on thev sill by the screw G.

The said sliding members C, D, may be frictionallylocked to each other, when desired, by the clamp E. The end of the tube C carries secured to it rigidly, a short sleeve e havin its outer end coned and its inner end threaed. An outer shell c has its inner bore in like manner coned at one end and threaded at the'other to correspond with and fit'res ectively the'co'ne end and threaded end 0 the sleeve e Both the sleeve and contiguous inclosed tube end are cross slotted with slots e to allow of bending. and contraction upon the inner tube D when the i f of the on f.

shell e is rotated so as by its screw'threads to be drawn in a longitudinal direction to compress the said coned parts upon the tube D. The reverse rotation of the shell e frees the tubes C, D from each other, so that they may slide freely in order to lengthen or shorten them to locate the attached shutter where desired.

The shutter can be frictionally locked any position either by the clamp E or by the brac et thumb screw 0. but most effectively against movement by the wind, by the concurrent use of both frictions. It is intended that the frictional engagement of the parts should always be made less than sufficient to resist a movement of the shutters by the strongest winds, so as to avoid the tearingof the shutters from their hinges in a hurricane, which can readily occur with the common unyielding positive shutter adjusters. My frictional stays yield when necessary to dangerous winds. They do not clatter and make noises under any circumstances.

My im roved sill pedestal is aflixed by one screw G aving just below its head a slight shoulder g? to press on the ball sha ed piece g and force the same firmly into t e orifice The lower 0 en end f 3 encircles snug y the washer or atef, which latter is fixed to the sill b nails or screws f The spherical lower end 0 ball g ma occupy various positions in the orifice f o the cup 7, allowing the latter to ada titself flat to the sill whatever its angle or s ope, while the screw G stands vertical as a pivot to the stay crease strains which can then only bend the screw by first-shearing the nails f 5 in the washer.

' My before mentioned shutter hook H is slotted lengthwise by a slot 1 and the separated parts are s rung 0 en a little before pivoting them wit the ase plate 6 The slotted shank furnishesside friction within the base plate to hold the hook from falling, thus keeping its upward position clear of the stay arm until pushed down over the latter.

In Figs. 9 and-9* I have -shown a shutter hook difiering from'that just described in the length of frictional bearing obtained for the slotted shank. I

I claim as my invention 1. A shutter stay having slidable stay rods, a friction bracket and two superposed pivoted connections-at right angles to each other between said bracket and stay rods whereb said parts have universal motion with re ation to each other, substantially as described.

2-. A shutter stay having slidable stay arms, a bracket, a plug adapted for frictional action within aforesaid bracket, said lug being provided with a vertically slotted ase adapted to receive the end of the stay arm .0 ening and said screw securing the base to t e sill, substantially as described.

5. A pivot pedestal for shutter stays, comprising a'disk secured to the sill, a cupped ase embracing said disk and a central pivot screw passing through the cup and disk.

In testimony whereof'I have signed my name to this specification, in the presence of two subscribing witnesses.

. THOS. A. WESTON.
